[IanMatthewHuff]

@ernurator Thanks for filing this. A quick question here. What language server are you using for the Python: Language server setting?

[ernurator]

@IanMatthewHuff Microsoft Python Language Server version 0.5.59.0

[IanMatthewHuff]

@ernurator Can you try moving that setting over to Pylance? Check to see if you get Intellisense after that change.

[ernurator]

@IanMatthewHuff it partially worked.

Now it doesn't show description of methods

[IanMatthewHuff]

We actually had a bug for this recently. We have the fix in, but it's not been released yet. Should be in our next extension release. I'm going to close this issue as a duplicate of the other issue on the topic.
#4218

[ernurator]

Okay, thanks!

[IanMatthewHuff]

If you still see an issue here after our next release (no date promises, but we usually release about every month) just ping back here and I'll reactivate this issue.

[ernurator]

@IanMatthewHuff problem still exists after new release

[IanMatthewHuff]

@ernurator You may be thinking of a release of the Python extension? This fix is in the Jupyter extension (which used to be part of the Python extension) and we have not yet made our release. You can check our release page in the marketplace here:
https://marketplace.visualstudio.com/items?itemName=ms-toolsai.jupyter
We've had a bit longer gap in our usual release due to the holidays and some large UI changes coming in the next release.

[ernurator]

@IanMatthewHuff okay, got it.
